PRINTING PLATE FOR ADDRESSING AND OTHER PRINTING MACHINES Filed April 9. 1929 //VYE/Y TOR Patented Mar. 1, 1932 UNITED STATES JOSEPH KBELL, F BERLIN-ZEHLENDORF, GERMANY PRINTING PLATE FOR ADDRESSING AND OTHER PRINTING MACHINES Application filed April 9, 1929, SeriaLNo. 353,747, and imGermany. April 16, 1927.

My invention relates to printing plates for addressing and other printing machines.

t is an object of myinvention to provide a printing plate of this type to which an independent identification tab may be secured, the plate and the tab being made as separate units. 1

To this end, I provide my plate with means for securing thereto an identification tab which tab, to facilitate handling, may be equipped with a handle.

Identification marks were heretofore applied to the plates themselves so that the plate and the mark could not be separated once the plate had been marked. According to my invention, I may combine any plate with any identification tab, and ex change the tab as desired.

In the accompanying drawings a printing plate embodying my invention, and its identification tab, are illustrated in perspective by way of example.

In the drawings Fig. 1 shows a plate viewed from the end to which my tab is secured.

Fig. 2 shows the tab viewed from its rear, and I Fig. 3 shows it viewed from its front face where an inscription may be provided.

Fig. 4 is a plan view of the plate with the tab in position.

Referring now to the drawings, 1 is the plate, 2, 2 are its upturned longitudinal edges, 3, 3 are horizontal flanges extending from the upturned edges, and 1, 4 are depressions which make up type on the other face of the plate.

At one end of the plate lugs 5 and 6 are made which project alternately on opposite sides of the plate.

These lugs serve for the reception of the tab 7 which on its rear faceis provided with folded-over flaps 8, 8 to engage the lugs gated, at one end of the tab 7.

The plates and tabs are made separatelyv as by punching, on a quantity production basis if desired, from sheet metal and the like, and the tab is secured to a plate by bending its flaps 8, 8 down upon the lugs 6, 6.

I claim:

1. The combination with an oblong printing plate of an identification tab, and cooperative engaging means on one end of the plate and on the tab for releasably connecting the tab to the plate in such a manner that it will be temporarily fixed perpendicularly to the plane of the printing plate.

2. An arrangement in accordance with claim 1, wherein the plate is provided at one end with alternately extending lugs while each tab is formed with opposed marginal flanges for slidably and releasably en- I gaging the lugs.

3. An arrangement in accordance with claim 1, wherein a handle is provided on one end of the tab and projecting in a direction opposite the engaging means thereon to facilitate the handling of the plate.

In testimony whereof I atfix mysignature.
